Answer:

File_object.read([n])

readline() : Reads a line of the file and returns in form of a string.For specified n, reads at most n bytes. However, does not reads more than one line, even if n exceeds the length of the line.

File_object.readline([n])

readlines() : Reads all the lines and return them as each line a string element in a list.

File_object.readlines()

Note: ‘\n’ is treated as a special character of two bytes

# Program to show various ways to read and

# write data in a file.

file1 = open("myfile.txt","w")

L = ["This is Delhi \n","This is Paris \n","This is London \n"]

# \n is placed to indicate EOL (End of Line)

file1.write("Hello \n")

file1.writelines(L)

file1.close() #to change file access modes

file1 = open("myfile.txt","r+")

print("Output of Read function is ")

print(file1.read())

print()

# seek(n) takes the file handle to the nth

# bite from the beginning.

file1.seek(0)

print( "Output of Readline function is ")

print(file1.readline())

print()

file1.seek(0)

# To show difference between read and readline

print("Output of Read(9) function is ")

print(file1.read(9))

print()
